The next time you go to a restaurant and order your favourite non-vegetarian dish, you might as well want to check on what it is that is being cooked and served to you.

In a recent case, 11 men were arrested for allegedly serving human meat in a Nigerian restaurant.

The grim discovery was made after police officers found two human heads wrapped in cellophane at a hotel's restaurant. The police had raided the hotel in Anambra in southeast Nigeria on a tip-off.

Among the 11 arrested is the hotel's owner.

Apart from the two human heads, the police also found two AK-47 rifles, 40 rounds of live ammunition and cellophanes from the unnamed hotel.

"I went to the hotel early this year, after eating, I was told that a lump of meat was being sold at N700 ($4)," a local pastor, who was one of those who tipped off the police, told the Osun Defender. "I was surprised. So, I did not know it was human meat that I ate at such an expensive price."
